Incorrect. The fewer guns available in society means that only the law abiding that would use them for self defense will have a lower number of them. Those who obtain them illegally are not going to see a drop in access. Guns are here to stay. You can't uninvent it and it's simply impossible to rid the world of them. It's not going to happen. Trying to do so only removes the source for those that would use them to defend themselves.
No one is talking about the possibility of "uninventing" guns or ridding the world completely of them. However, if guns are made less easily accessible, then the number of shootings will surely decrease. Sure, maniacs who wish to get guns illegally will always be able to - I don't think any society will ever be able to rid itself completely of the occasional tragic mass murder spree such as that which inspired this thread. There is however a strong likelihood that there will be fewer one-off acts of violence caused by ordinarily law-abiding citizens, if guns were outlawed. It's the most obvious deadly weapon there is for those temporarily alienated by society, going through a difficult stretch in their life etc. to kill someone if things get a bit too tough for them to handle.
Oh and by the way, I don't know why you argue in such an arrogant way, baldly stating "Incorrect" as if it were a fact that your opinion is the truth. It's probably because as a US marine, you love guns and think everyone should have one, and have difficulty accepting others' viewpoints. Certainly I have encountered few people as dogmatic as you.
Exactly the same? Of course not. The problem is the assumption that you're actually making it more difficult to obtain one and it's simply not true. Any time you make something illegal you increase its availability in the black market.
So you admit that the number would be lower. Thanks.
